Other possibilities are:

 - moving code to a helper function often removes extra indentation
 - shorter identifiers (e.g. as a side effect of moving code to a helper
   function)

		local function swap_1_2(t) t[1], t[2] = t[2], t[1] end

		swap_1_2(menu_entries)

  or 

		local function swap(t, i, j) t[i], t[j] = t[j], t[i] end

		swap(menu_entries, 1, 2)
